In Vitro Effects of Combining Resin Infiltration and At‐Home Bleaching on Hydrogen Peroxide Penetration, Color Change and Enamel Morphology

open access: yesJournal of Esthetic and Restorative Dentistry, Volume 38, Issue 10, Page 1947-1956, October 2026.
ABSTRACT Objective To evaluate the effect of resin infiltration (RI) prior to at‐home bleaching on hydrogen peroxide (HP) penetration into the pulp chamber, color change, and enamel morphology in human teeth with sound enamel or white spot lesions (WSLs), using different RI protocols.

Challenges and Opportunities for Layered Double Perovskite Solar Cells

open access: yesSolar RRL, Volume 10, Issue 17, 15 September 2026.
Layered lead‐free double perovskites suffer from intrinsic and extrinsic limitations that hinder high photovoltaic performance. This review identifies key challenges, including unfavorable band structures, strong self‐trapping, defect‐induced recombination, processing‐induced inhomogeneity, and device‐level mismatches.

Boosting Efficiency and Stability of Air‐Processed Blade‐Coated All‐Polymer Organic Solar Cells Based: The Role of Electron Transport Layer and Additives

open access: yesSolar RRL, Volume 10, Issue 17, 15 September 2026.
All‐polymer PM6:PY‐IT solar cells processed by blade coating in air using o‐xylene are studied alongside a PM6:Y12 binary reference and an advanced ternary PM6:Y12:PY‐IT system. We examine electron transport layers and additives to tune morphology, charge transport, and device efficiency. Characterization includes J–V, GIWAXS, AFM, and SCLC.

Decoupling Transparency and Electron Injection in Ultrathin Ag Electrodes Using an Al/MoO3 Double Seed Layer for Transparent Quantum Dot Light‐Emitting Diodes

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
Transparent quantum dot light‐emitting diodes (Tr‐QLEDs) employing an Al/MoO3 double seed layer decouple optical transparency from electron injection in ultrathin Ag electrodes. The functionally separated seed layers enable low optical loss and efficient charge injection simultaneously, resulting in improved electroluminescent performance, enhanced ...

Intrinsic Interfacial Energy Alignment Enables ETL‐Free Organic Solar Cells

open access: yesAdvanced Functional Materials, Volume 36, Issue 71, 3 September 2026.
Molecular orientation of the small‐molecule donor BTR‐Cl induces a vacuum‐level shift that pins the Fermi level at ∼4.4 eV at the active layer/Ag interface, enabling Ohmic contact formation without an electron transport layer. This strategy is extended to ternary PM6:Y6:BTR‐Cl devices, achieving an ETL‐free efficiency of 18.6% with enhanced operational
